If Harry was three years older, he would be more mature physically and mentally. This could mean he is less likely to be bullied by Dudley, as he would be stronger and more assertive. At Hogwarts, his academic performance might be even better as he has had more time to study independently before coming to school. His relationships would also be different. For instance, his friendship with Ron and Hermione might have a different start, as he would be more self - assured and might approach them in a different way.
A three - years - older Harry Potter would bring a significant shift to the story. His Patronus could be more powerful and perhaps have a different form, as his experiences and emotions would be more developed. In the fight against Voldemort, he might be able to anticipate the Dark Lord's moves better. He could also be more involved in the Order of the Phoenix's activities earlier. His presence could inspire more students to join the fight against the dark forces, and he might be seen as a more natural leader among his peers, which would change the power dynamics within Hogwarts and the wizarding world as a whole.
It would likely change the power dynamic. The sister could be a popular and powerful figure at Hogwarts. She might be in a different house than Harry, which could lead to some friendly rivalries between the houses in a different way. For example, if she was in Slytherin, there could be more cooperation between Gryffindor and Slytherin because of their family bond.
Regarding the relationship with the other houses, the older brother could be a Hufflepuff or a Ravenclaw. If he was a Hufflepuff, it might make the Hufflepuffs more friendly towards Harry as they would see him as related to one of their own. If he was a Ravenclaw, the Ravenclaws might expect Harry to be as intelligent as his brother, which could lead to some interesting interactions and challenges for Harry at Hogwarts.
Harry would probably be more empathetic towards non - human magical creatures. The Mosasaurus is so different from the usual magical creatures he encounters at Hogwarts. He would understand the needs and feelings of these large and perhaps misunderstood creatures better, which could change his approach to dealing with all magical creatures in general.
The story would change a great deal. His identity within the wizarding world would be questioned. People might be afraid of him or see him as an outcast. His ability to interact with others would be different. He might be more solitary due to his Lamia nature.
If Harry Potter was trained by Constantine in fanfiction, the story would change drastically. Firstly, Harry's character development would take a different turn. He'd be more likely to question the black - and - white view of good and evil that he had at Hogwarts. Secondly, the plot would involve more elements from Constantine's universe, like dealing with hellish creatures. The battles would be more complex as Harry would use Constantine - like tactics. Also, his relationships with other characters, especially those from Hogwarts, might become strained as he gets involved in a more dangerous and morally ambiguous form of magic.
The story would be drastically different. Harry's personality would be molded by Klingon values. He'd be more bold and confrontational. His approach to learning magic would be different too. Instead of learning from books in a classroom, he might learn through practical combat - like situations. His relationships with other characters would change. For example, Hermione might not be as close to him as she is in the original, because her studious nature might not be as valued in a Klingon - influenced environment.
If Harry Potter becomes a Hollow in fanfiction, the entire narrative would be overhauled. The traditional plotlines of him fighting against the dark forces in the wizarding world would be replaced. His friends would no longer be able to rely on him in the same way. For example, his Gryffindor courage might be replaced with a more reckless and dangerous behavior. His magical abilities could be used in unpredictable and harmful ways. The Hogwarts environment would also change as the school tries to deal with the threat that a Hollow - Harry presents. Teachers would have to figure out new ways to protect the students, and the once - safe haven of Hogwarts could become a place filled with fear and uncertainty.
The story would be drastically different. Harry might not oppose Voldemort. He'd be on the 'dark side' instead. His Hogwarts experience would be non - existent or very different if he even went there. He'd probably use the dark arts more often.
His magical abilities would be used in a different context. Instead of using magic mainly for school competitions or fighting Voldemort's Death Eaters, he'd be using it to combat vampires, ghouls, and other supernatural beings that Hellsing faces. His view of good and evil might also change. In the wizarding world, there were clear lines between good wizards and bad wizards. But in Hellsing, the lines between what is acceptable in the fight against evil can be blurred.
If Harry had no eyes, his experience at Hogwarts would be transformed. He couldn't read textbooks in the traditional way. Maybe he would use magic to have the words read to him. His interactions with magical creatures would be different too. For example, when facing a basilisk, he couldn't look it in the eye to defeat it, so he would have to find another way, perhaps using his sense of smell to detect its presence and then cast spells blindly in its direction.
